I v EssnL-nMsING APPARATUS.

1,300,553. l p r county of Pierce and State of Washington,

. and Bellingham, in the countyof Whatcom and State ofWashington, respectively, have invented certain new 'anduseful-.Improvements inLVessel-Raising Apparatus; and they do herebydeclarethe following to be a f full, clear, and exact description ofthe invention, such as will enable others skilled in the artto which it appertains to make and use the same. Y. Y .l

, This' invention is anI improvement .in ships andjhas 'particular reference-.teau apparatus for detecting the location of sunken vessels and raising the same.

vAn. object of the invention. :sto provide` anv .improved apparatus including a buoy which remains upon the surface after a'vesi sel has` sunk in order to indicate the Location thereof and which remains connected to the f vessel so that a lifting or raising device may be lowered and automatically connected to a hook member carriedy byl the vessel.

Another object is the provision of an apparatus of this character which is simple in construction, easy to manufacture andapply to a vessel and effective in c arryingout the purpose ,forV which it isdesigned. c

The inventive idea involved is capabley of receiving a variety ofsmechanical expressions one of which, for the purpose of'illustrating the invention, is shown in the accompanying drawing wherein q Figure 1 is a fragmentary longitudinal section through a vessel showing the apparatus applied thereto and in its inoperative position.

Fig. 2 is a view illustrating the position of the parts of the apparatus when the vessel has been sunk.

Fig. 3 is a fragmentary transverse section through the vessel showing portions of the apparatus in elevation.

Fig. 4 is an enlarged fragmentary longitudinal section through the hook member employed in connection with the invention.

Referring more particularly to the drawing, the numeral 5 indicates a vessel which may be of any desired construction and mounted upon one or more of the decks of the vessel at any desired point is a vertically disposed guiding and supporting frame 6 in BENJAMIN N. BART.-v

, which is normally mounted a buoy 7 of any desired construction and carrying a signal plateV 8 upon the top thereof which may be discernible when'the buoy is floating `upon the surface.

Preferably ysituated below the deck upon.,

which the frame 6 is mounted, is acasing ,9 in which is rotatably mounted a drum'lO having a cable 11 .wound thereon and connectedy at 12 to the buoy 7. By-reason of thisv connection with the buoy it will be apparent that when the vessel sinks and the buoy is detached from the frame 6.and remains floating upon the surface the cable 11 will be automatically unwound from the eo, Y

drum 10 until the vessel settles upon the Y bottom. Y

.The apparatus furtherl comprises a hook member 18 having an enlargement 14 upon f its shank which is adapted to be secured to the deck of a vessel at a point adjacent'theY frame 6. and `the attachment of the hook member tothe vessel is reinforced by abar 15 forming an extensionof thehook and preferably projecting to the-keel of the vessel where the same is attached so that kthe hook will `be suiiiciently anchored to withstand lthe stress applied thereto when the vessel is being raised. The ibill 16V of the hook member is provided therein with -a longitudinally extending` opening .17 through Y which the cable 11 passes and thelower end of said opening is ared or enlarged as indicated at 18 Vfor a purpose ,which will presl ently appear. The cable 11 is of sufficient .lengthto permit of the vessel sinking .toa

considerable depth before Vthe cable is entirely unwound from the drum and attached to the end of the cable on said drum is a stop or plug 19 which will engage in the enlargement 18 of the opening 17 after the cable has been entirely unwound from the drum 10 and said stop or plug 19 will prevent detachment of the cable from the hook member and thus nrovide a constant connection between the latter and the buoy 7 The cable 11 provides a guide for attaching a hoisting element 20, preferably in the form of a large ring, which is adapted to engage with the bill of the hook member 13 when it is desired to raise the vessel but before lowering the lifting or hoisting element 20 along the cable 11 it is essential that the latter be entirely unwound from the drum 10 so that the plug or stop 19 will engage in thelower end of the opening y 17. Ihering 2,0is secured,tooneendofa hoisting table 21, the other end' of which may be wound upon a drum of a suitable wlndlass mechanism (not shOWIlwbyfwhich a vessel may be raised. As the hoisting ring is lowered along the `cable 1l of theguide the same will eventually engage the bill 16i of the hook member 13 andthentpulling:A upwardly upon the cable 2l the ring 20 may be caused toengagethebight 22 ofIk the hook' member Awhereupon the'apparatusv will be inAv postion forv the hoisting orfraising. operation. vInorder to insure the retention ofthe lifting ring 20 in engagement withfthehool member the latter is provided with' aflockinggbarQ -pivoted at 24130 the shank of the hook member andV extending across the space l' between .'Sai'dlghank andi` of the -bill 1.6 whe-re the free fend'V of said bar engages a vlug-25`` on said bill so that the bar'may `ber-swunginw'ard'ly when theflifting ring is engagedy therewith afterfwhich said bar will return to tsnormal positionv and thus close theA space betweenthebill and-shank of the-hook member. i

What is claimed is Y l. Inan apparatus of the class described, the'combination with a vessel; of a hook member secured thereto and having a bill'A portion provided with a longitudinal eX- vtending opening thelower end of which isenlarged, adrum carried by the vessel, a cable normally wound upon said drum and passing through said opening in the bill of the 'hook member, a stop secured to-the end ofthe cablewound upon the drum andv adapted :to engage in thegenl'arged` portion of said opening when the cable is entirelyY -unwoundfrom the drum whereby topermanently-maintain-the cable in connection with the'hoo'k member, a buoy adapted-to remain afloat when the vessel sin-ks and connected Vtothe cable lto unwind the saine, and av hoisting.. element Vadapted to be lowered along fsf/aid.: Cable ands v-@lidadthereby into engage ment with the bi l of said hook member to' permit of the raising of the vessel.
